| Zusammenfassung: | To improve the productivity of a laminated iron core.SOLUTION: A method for manufacturing a laminated iron core includes an insertion step, an injection step, and an air blow step. The insertion step includes inserting a columnar magnet to penetrate a laminate obtained by laminating a plurality of iron core pieces. The injection step includes injecting resin between the laminate and the magnet. The air blow step includes performing air blow to the laminate from at least one of above and below the laminate, while floating the laminate with respect to a lower jig located below the laminate.SELECTED DRAWING: Figure 4A
【課題】積層鉄心の生産性を向上させること。【解決手段】積層鉄心の製造方法は、挿入工程と、注入工程と、エアブロー工程と、を含む。挿入工程は、複数の鉄心片を積層させた積層体を貫通するように柱状の磁石を挿入する。注入工程は、積層体と磁石との間に樹脂を注入する。エアブロー工程は、挿入工程と注入工程との間に、積層体の下方に位置する下治具に対して積層体を浮かせながら、積層体の上方および下方のうち少なくとも一方から積層体に対してエアブローを行う。【選択図】図４Ａ |
